What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Repeat imaging when regional and remote patients with stroke arrive at a comprehensive stroke center can delay endovascular thrombectomy. We examined outcomes amongs patients transferred for endovascular therapy from nonmetropolitan primary stroke centers. Methods: In this prospective observational study patients who were transferred from remote nonmetropolitan hospitals with large vessel occlusion were recruited between 2020-2023. The control group was defined as patients with repeat neuroimaging at the comprehensive stroke center in the radiology/emergency department. Direct-to-angio (direct to angiography) included patients who proceeded directly to the angiography suite without any repeat neuroimaging or routine flat panel computed tomography. Logistic regression with propensity matching was performed to assess factors associated with 3-month independent outcome (modified Rankin scale score 0-2). A secondary analysis was performed to assess factors associated with recanalization. Results: Between June 2020 and February 2023, 227 patients with large vessel occlusion were transferred for endovascular clot retrieval. A total of 47 (26%) patients recanalized by time of arrival and 180 had persistent large vessel occlusion. Primary stroke centers were a median distance of 185 km from the comprehensive stroke center (interquartile range 130-256). After propensity matching 138 patients remained. Characteristics between direct-to-angio and control groups were similar with regard to age (68 versus 66), primary stroke centers National Institutes of Health Stroke Scale score (15 versus 13), and onset to referral (200 versus 246 min). Direct-to-angio increased independent functional outcome at 3 months (adjusted odds ratio, 2.2 [95% CI, 1.0-4.9]; Conclusion: In patients who have already received telestroke review at the primary stroke centers, our results suggest a direct-to-angio approach is likely to result in better outcomes.
